Collar choice (safety issue)

Need some advice here...my lab normally wears a collar with a blastic buckle. However, yesterday while outside on his run in the backyard, he "bolted" (my wife saw it happen, I was at work), and literally snapped the plastic, becoming free in the process. My initial though was to buy one with a metal buckle- one that wouldn't break. But, is it worth being able to break free, should he get caught up in something? Thanks for your advice in advance.

I'm not a big fan of leaving dogs out unsupervised. Recipe for something bad to happen. If you are going to use a collar I would advise a Coastal 1" Double Ply nylon collar. They have a metal buckle and are not breaking.

I use Gundogsupply.com and have gotten some great collars from there. They have really good nylon with metal ring collars that they will rivet a name tag onto it for free. I have had great luck with it holding up being wet every day, worth checking out.

personally i dont keep a collar on my dog to many bad things can happen with a collar on. the only time she has a collar on is when i go to the vet but other than that never has a collar on if i go for a walk with her she and put her on a slip lead.
